Alternatives to building an I/O subsystem with multiple disks to improve the I/O performance are considered. There exist several alternative ways to configure a number of disks to achieve a higher performance. Specifically, the authors consider disk synchronization, data declustering/disk striping, and a combination of both these approaches. The effects of block size and other parameters of the system are evaluated. Through simulations, it is shown that disk synchronization is a better alternative at low request rates and data declustering is a better alternative at higher request rates.
